ABSTRACT:
A nozzle head includes a nozzle carrier so mounted to a stationary housing as to allow rotation thereof about a longitudinal axis by a recoil action caused by pressure water exiting spray nozzles accommodated in the nozzle carrier, and a hollow shaft rotatably supported in the housing and secured to the nozzle carrier. The hollow shaft has a central passage for conducting pressure water to the spray nozzles; and has a pressure water connection proximate end face which is supported by a first sealing disk of highly wear-resistant material, e.g. ceramics. The first sealing disk is connected to the hollow shaft via a mounting so as to conjointly rotate with the nozzle carrier and hollow shaft during operation of the nozzle head. The shaft-distal end face of the first sealing disk bears upon a second stationary sealing disk which is also made of a highly wear-resistant material, e.g. ceramics, and received in a mounting which is fixed via a seal ring in the housing.
